SPECIFICATION forming part of Letters Patent No. 742,149, dated October27, 1903. Application filed April 16, 1903. Serial No. 152,906. (Nomodel.)

2'0 all whom it may concern.-

Be it known that I, GEORGE FRANKLING BAXTER, a citizen of the UnitedStates, residing at Singer, in the parish of Oalcasieu and State ofLouisiana, have invented certain new and useful Improvements .in SawmillOarriages; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as willenable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawing, and to the figures ofreference marked thereon, which form a part of this specification,

This invention relates to reciprocating sawmill-carriages; and theobject of the invention is to provide means for automatically reversingthe motion of the carriage if it should happen to get away from thesawyer.

A further object of the invention is to produce a cheap and simpledevice for the purpose stated which may be easily constructed even byunskilled persons.

Speaking generally,it consists of a trippinglever at each end of thecarriage-track in position to be struck by the carriageand connected tothe reversing-lever of the engine to operate the same.

In the accompanying drawing the figure is a side elevation of theapparatus.

The drawing shows a carriage (indicated at 6) running on a track Z, thesaw at 8, and engine (indicated at 9) of the twin orreversing type, anda drive-cable at 10, which is connected to the carriage and operated bythe'engine and passes over pulleys 11 at opposite ends of the track. Thesawyers reversing-lever is indicated at 12 at the stand beside the saw,and this lever is connected to the engineand apparatus to reverse thesame. These parts are all old and well known and are thought to requireno further description.

The reversing apparatus invented by me is placed at each end of thetrack to limitthe run of the carriage, and a description of one willanswer for both. 13 indicates a bent tripping-lever, which is pivoted at14 to the frames of the track, and its upper arm projects above theplatform and track in position to be struck by the end of the-carriage.Its lower arm is connected to a rope 15', which passes around a pulley16 and thence to the connection with the reversingvlever at 17.

When the carriage reaches the end of the track, if the reversing-leveris'not thrown by the sawyer it will strike the tripping-lever 13 and bymeans of the rope connection throw the reversing-lever to reverse theengine and the run of the carriage. I

To return the tripping-lever 13 to its original position after thecarriage leaves it, aweight 18 is employed. f This weight hangs from alever 19, pivoted'at 20 to a frame of the track and connected by a 'bar21 to the tripping-lever. When the carriage leaves the lever, the weightlifts the latter to its original position.

What I claim as new, and desire to secure by LettersPatent, is-- Thecombination with-a track and a reciprocating carriage thereon, adriving-motor connected to the carriage, and a reversinglevercontrolling the motor, of a tripping-lever at each end of the track, inthe way of the carriage, and adapted to be thrown when struck thereby,means to restore each lever after the carriage leaves it, and a ropeconnection between the tripping-levers and the reversing-leverpermitting slack when the lever is restored.

In testimony whereof I aftix my signature in presence of two witnesses.

GEORGE rnlmmne BAXTER.
